BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for preventing derailment and lifting of wheels of a vehicle running on rails.

Conventionally, in water purification plants, etc., as means for efficiently settling solids contained in the water to be treated, an inclined plate sedimentation device, in which a plurality of inclined plates are attached to a support frame and integrated, is used as a hanging means such as a hanging bolt. known is a tilt plate settling system suspended in a settling tank. FIG. 4 is a diagram schematically showing the configuration of an example thereof, viewed from the direction of water flow. In FIG. 4, 50 is a sedimentation tank, and 60 is an inclined plate sedimentation device. It is suspended so as to be submerged in treated water (not shown). The suspending bolt 70 is attached to a suspending member 90 that spans over the sedimentation tank 50 at its upper end.

In the system of FIG. 4, the wheels 42 are attached to the suspension material 90, and the rails 41 for the wheels 42 to run are arranged on the base around the opening of the sedimentation tank 50, and inclined as necessary. Means are provided to move the plate settler 60 . If necessary, there is a case where a covering means is provided on the sedimentation tank 50 to block the irradiation of sunlight. The cover means can be opened and closed with.

When the suspension member 90 and the carriage are made movable by such a combination of the rails 41 and the wheels 42, the wheels 42 may shift horizontally from the rails 41 in the event of an earthquake and may derail due to strong winds. There is a risk that the wheels 42 may be lifted from the rails 41 by the truck being swayed, and it is necessary to take measures to prevent these wheels from coming off or lifting.

As a lifting prevention means for a combination of a rail and a wheel, for example, Patent Document 1 discloses that a rail having a shape whose upper end is wider than its central portion is used, and claws 5 attached to a moving body are used to lift the rail. An arrangement is disclosed that embraces the upper end.

BRIEF DESCRIPTION OF THE DRAWINGS It is a figure which shows typically the structure of one Embodiment of the derailing / lifting prevention structure of this invention, (a) is sectional drawing of the width direction, (b) is a side view. FIG. 2A is a cross-sectional view taken along line A-A' in FIG. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a diagram schematically showing the configuration of an example of an inclined plate sedimentation system to which the present invention is applied; It is the figure which looked at the wheel peripheral part of the traveling body of FIG. 1 from the side.

The derailment/floating prevention structure of the running body of the present invention is arranged near the rail on which the wheels of the running body run, and includes a square pipe and a guide that encloses the square pipe, and the square pipe is fixed in the longitudinal direction. Secured to the base of the running area via spaced support members, the guide includes openings through which the support members can pass and rotates as the support members pass through the openings. The present invention is characterized by comprising a stopper that does not hinder passage of the support member and always supports the opening from the lower surface side of the bottom plate.

Hereinafter, the present invention will be described in detail with reference to embodiments.

FIG. 1 is a diagram schematically showing the configuration of the vicinity of the derailing/lifting prevention structure of one embodiment of the running body equipped with the wheel derailment/lifting prevention structure of the present invention, viewed from the front in the running direction. is. In addition, in FIG. 1, only main components are shown, and other components are omitted for the sake of convenience. In FIG. 1, reference numeral 20 denotes a running body, for example, a carriage equipped with a suspension member 90 that suspends the inclined plate sedimentation device 60 shown in FIG. However, the present invention is not limited to these. The traveling body 20 has wheels 42, and the wheels 42 travel on rails 41 installed on the base 30, thereby traveling in a direction perpendicular to the plane of the drawing.

In FIG. 1, 10 is a derailing/floating prevention structure of the present invention, FIG. 2 is an enlarged view thereof, and FIG. , and FIG. 2(b) is a side view. 2(a) is a cross-sectional view taken along line B-B' in FIG. 2(b), and a cross-sectional view taken along line A-A' in FIG. 2(a) is shown in FIG. 3(a).

In the derailment/floating prevention structure of the present invention, a long square pipe 15 parallel to the rail 41 and a square pipe 15 having a cross-sectional shape similar to that of the square pipe 15 in the width direction are installed near the rail 41. It has a guide 11 to be included. The square pipe 15 has a top plate 15a, two side plates 15b and 15b and a bottom plate 15c, and the guide 11 has a top plate 11a, two side plates 11b and 11b and a bottom plate 11c.

Both the square pipe 15 and the guide 11 are arranged so that the bottom plates 15c and 11c are parallel to each other in the horizontal direction. In addition, the upper end of a rod-shaped support member 17 is attached vertically to the lower surface of the bottom plate 15c of the square pipe 15 at intervals in the longitudinal direction, and the lower end of the support member 17 is fixed to the base 30 side. The square pipe 15 is fixed to the base 30 via the support member 17 . In this embodiment, as shown in FIG. 2A, the substrate 16 is fixed on the substrate 30, and the lower end of the supporting member 17 is fixed to the substrate 16. As shown in FIG. The guide 11 is attached to the traveling body 20 via an attachment member 12 attached to the top plate 11a.

The guide 11 is short in the longitudinal direction of the square pipe 15, and an opening 11d is formed at the center of the bottom plate 11c of the guide 11 in the width direction to bisect the bottom plate 11c along the longitudinal direction. When the traveling body 20 travels, the support member 17 passes through the opening 11d.

When the traveling body 20 shifts in the horizontal direction due to an earthquake or the like, the guide 11 also tends to shift in the horizontal direction. and prevents the traveling body 20 from shifting in the horizontal direction. Further, when the running body 20 is swayed by a strong wind or the like, the guide 11 also tries to float upward, but the upper surface of the bottom plate 11c of the guide 11 abuts the lower surface of the bottom plate 15c of the square pipe 15, and the running body 20 is prevented from floating upward. In the present invention, since the square pipe 15 and the guide 11 having a cross section similar to that of the square pipe 15 are used, when the guide 11 is displaced, the surfaces of the guide 11 come into contact with each other. Since the movement suppressing effect is high and the stress per area applied to the inner surface of the guide 11 and the outer surface of the square pipe 15 is small, deterioration of the guide 11 over time is suppressed.

Also, in the present invention, a stopper 13 is arranged below the guide 11 . The stopper 13 has a cross shape including a rotating shaft 13a and four rotating blades 13b projecting in four directions from the rotating shaft 13a. The rotary shaft 13a is rotatably attached to one of the lower surfaces of the bottom plates 11c, 11c of the guide 11 divided by the opening 11d of the guide 11. As shown in FIG.

3(a) is a cross-sectional view taken along line A-A' in FIG. 2(a), and FIG. 3(b) shows a state in which the stopper 13 is rotated 45 degrees from the state in FIG. 3(a). As shown in FIGS. 3(a) and 3(b), regardless of the rotational position of the stopper 13, one of the four rotor blades 13b is always positioned on the bottom plate of the guide 11 to which the rotating shaft 13a is attached. From one of 11c, 11c, it reaches the bottom plate 11c of the other beyond the opening 11d, and the end portion side of the rotor blade 13b overlaps the lower surface of the bottom plate 11c of the other. Therefore, when the traveling body 11 tries to float up in strong wind, the bottom plates 11c, 11c of the guide 11 also float up, and the upper surfaces of the bottom plates 11c, 11c come into contact with the lower surface of the bottom plate 15c of the square pipe 15. The rotor blade 13b supports the bottom plates 11c, 11c from below, and the bottom plates 11c, 11c receive the pressing force from the bottom plate 15c of the square pipe 15, thereby preventing the opening 11d from widening.

Also, when the support member 17 passes through the opening 11d of the guide 11, the support member 17 abuts against the rotary blade 13b of the stopper 13. hits the rotor blade 13b, which is pushed by the support member 17 and rotates. Therefore, the support member 17 can pass through the opening 11d while pushing and rotating the rotor blade 13b.

In order to support the bottom plate 11c of the guide 11 from the bottom side, the rotor blade 13b preferably has a flat top surface. It is preferable to have a gap of about 0.5 mm to 2 mm between them because there is a risk of damage due to sliding against each other.

The material of the square pipe 15, the guide 11, and the stopper 13 (rotating shaft 13a, rotating blade 13b) is preferably stainless steel in consideration of durability. In FIG. 1, only one of the left and right wheels of the running body 20 is shown, but the derailment/uplift prevention structure of the present invention is attached near each of the pair of left and right wheels of the running body 20. Since a plurality of wheels are normally used along the running direction, it is preferable to attach the floating structure of the present invention to each wheel.

Moreover, as for the positional relationship between the wheels 42 and the guides 11 in the running direction, it is preferable to displace them back and forth and arrange them close to each other, as shown in FIG. 5 is a schematic diagram seen from the right side of the paper surface of FIG.
